CONSULT-II Function (AUTO DRIVE POS.)NIS00260
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector (1).
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “AUTO DRIVE POS”.
If “AUTO DRIVE POS.” is not indicated, refer to GI-40, "
CON-
SULT-II Data Link Connector (DLC) Circuit" .
